i have used this oil for about 125 k miles and can say it does good ,it doesn't break down between oil changes or gum up motor i usually change oil about every 5 to 6 thousand miles ,i have around 1 56 k on the motor ,its a very good oil full synthetic and keeps my motor clean ,i always do my oil changes because its easy and more convenient for me ,i would highly recommend using Havoline full synthetic with dexos . its exactly 6 quarts and easy poor plastic container makes eco and user friendly .

The Havoline 5W-30 Full Synthetic seems to have the high quality I require at a good price. Like the fact the Havoline is available as a six quart pack--avoid having to look for a matching pricey single quart to add to a five quart jug for pickups and SUVs with six quart refills. A major drawback to home oil changes (and thus sales of this product as non-bulk) now are all the skid plates, noise, and air dams blocking access to the drain plugs %26 filters--very difficult to impossible to remove them to change oil at home! And, all the goofy drain plugs for my newer Fords--the Valvoline shops tend to suck the old oil out the dipstick tube unless you request/demand them draining it from below. The local Valvoline change station allows customers to bring their own (the Havoline and the Ford OEM filter that I prefer)--but lately seem give less and less credit toward the total bill. Despite good oil changes at Walmart Auto centers years ago, as a senior citizen I tend to skip them now altogether due to poor tire work, damaged lugnuts, lack of proper tools, employee turnover, etc.
